When you think about where your hips should be, remember that the deadlift is a pull and not a squat. You cannot squat a heavy deadlift off the floor. The deadlift is a back exercise first and foremost.

I personally start all deadlifts with the bar over the middle of my foot, take my grip without moving the bar, touch my shins to the bar and shove my knees out without moving the bar, and then squeeze my chest up to set my back. This means the bar is over the middle of my foot when I go to pull, and the height of my hips is completely dictated by my anthropometry and not some random vision of what I think my start position should look like.
